The soap continues, within a day my T-key started sending the signal for Hiragana-Katana. I just found out that the service center flashed an old version of the BIOS 56cn38ww, while 56cn43ww is the newest. I am really unhappy with this situation.
Conclusion: the problem is resolved by flashing the BIOS with any version. The problem occurs afaik (at least) with 56cn38ww. It's almost like the bug reprograms the keyboard. I have a strong feeling that it is linked to switching between X and a virtual terminal (in text mode). I think the problem started when I switched from a text terminal (where I ran apt-get as super-user) to X where I was logged in in Gnome. I think somehow pressing ctrl+alt+fn+F2 (switch to text terminal 2) or ctrl+alt+fn+F7 triggered the bug to mess up the T-key. (I might have accidentally pressed shift as well, or maybe missed an alt or ctrl once, it's surprisingly hard to press the right keys+fn if one's used to doing it on muscle memory alone.) This T-key-thing happened to me twice now, and the first time I remember having the same feeling about it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/974455 Title: Lenovo u300s 't' key sends "Hiragana-Katana" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/974455/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
